Since 1999, the county's Department of Natural Resources and Parks (DNRP) has commissioned a water quality survey to get feedback on water quality issues from King County residents.

The survey is conducted by an independent research firm that randomly polls 400 King County residents age 18 and older.

The survey helps us understand how we're meeting our values and goals, allows residents to rate environmental issues in our region, and measures support for recycled wastewater products (biosolids, reclaimed water) and increased funding for services.

King County DNRP used to conduct the survey annually, and made a decision in 2007 to do it every two years as a cost-saving measure. We will commission the next survey in 2017.
